Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616656, here are decompositions:

53 + 31616603 = 31616656
233 + 31616423 = 31616656
263 + 31616393 = 31616656
293 + 31616363 = 31616656
317 + 31616339 = 31616656
359 + 31616297 = 31616656
587 + 31616069 = 31616656
647 + 31616009 = 31616656

Showing the first eight; more decompositions exist.
